System Data

Mani-Frant System

The primary is Mani, an ordinary red main sequence star. It has a luminosity of 0.0202 Sols, a mass of 0.3942 Sols, and a diameter of 604,000 km. (I) Frant, designated the mainworld, (II) a very thin atmosphere radworld, and (III) a vacuum iceworld form the inner part of the outer zone – orbital positions (IV) through (VIII) are unavailable due to the presence of the companion star. (IX) a small ice giant, (X) a ringed large gas giant, and (XI) an exotic atmosphere bigworld form the outer part of the outer system. Many of the worlds retain satellites.

Obess Subsystem

The companion is Obess, a dim red subdwarf star that orbits Mani at 3.08 AU (orbital position (VI), 172 million km) and has an orbital period of 1 year 352 days. It has a luminosity of 0.00103 Sols, a mass of 0.081 Sols, and a diameter of 109,000 km. (I) a vacuum iceworld, (II) a thin atmosphere bigworld, and (III) a ringed small gas giant form the outer system. The gas giant retains satellites.

Mainworld Data

(I) Frant

(I) Frant is designated the mainworld. It orbits Mani at a mean distance of 0.19 AU (28.4 million km), within the outer zone. It has an orbital period of 48 days 4 hours: it is tidally locked to Mani. The axial tilt is 14 degrees. Frant has a diameter of 8,077 km, a density of 5.38 g/cm³, and a surface gravity of 0.62 G. Tidal stresses generated by the gravitational pull of Mani cause frequent geological activity. Its atmosphere is rated as Thin, with a mean surface pressure of 0.31 bar and a composition of 81% nitrogen (N2), 18% oxygen (O2), and 1% argon (Ar), water vapor (H2O), carbon dioxide (CO2), neon (Ne) and other trace gases. Approximately 13% of the surface is covered in seas of liquid water: average tidal ranges exceed 0.1m. Mean surface temperature: -63°C. The climate is rated as Very Cold and is static, with no seasonal changes during the local year. The atmosphere is sluggish and weak weather systems driven by the star drift across the globe.

Mainworld Geography and Topography

Total surface area: 205 million km², Land surface area: 178 million km², Water surface area: 27 million km².

  • Frant is a Twilight Zone World.
  • The world experiences libration, which causes the star to move in the sky and periodically rise and fall above the horizon in the twilight region.

Native Lifeforms

Mani-Frant System

Frant, the mainworld, has extensive native life, consisting of microscopic organisms, stromatolite-parallels and primitive flora that can be found in almost every ecological niche. Their metabolic functions drive the process of atmospheric renewal.

No other world in the system is known to have native life.

Obess Subsystem

No world in the subsystem is known to have native life.

History & Background (Dossier)

No information yet available.

World starport

Frant has a routine quality starport.

  • A Class-C Starport Facility has minimal if any shipyards and can only perform extremely limited repair work.
  • This facility has many very skilled personnel who can perform surprisingly sophisticated repair work despite the limited facilities.
  • This facility has refueling infrastructure and limited refining capabilities. One may purchase unrefined fuel here.
  • Starports of this class rarely have both a Lowport and a Highport.

World technology level

Frant possesses a Technology Level of TL–10 or TL-A in Hexadecimal Notation.

World government

Frant has no well-defined government structure.

  • In many cases, tribal, clan or family bonds predominate.
  • The typical power source of this government is an Pantocracy or Chaos.
  • The typical power structure of this government is a Confederation (Anarchy).
